Colonel Jack O'Neill is the wry, battle-scarred soldier who leads the flagship SG-1 team through the gate. Pulled back into service after the events of the original film, he masks a sharp tactical mind and deep loyalty behind a steady stream of sarcasm and pop-culture jokes.
Across the series O'Neill grows from a grieving widower hardened by personal loss into a leader who fiercely protects his team and, increasingly, the whole planet. His bristling distrust of bureaucracy never fades, but his bond with Carter, Daniel, and Teal'c becomes the emotional core of the show.
By the later seasons he is promoted to general and takes command of Stargate Command itself, trading front-line missions for the burden of running Earth's defense. Richard Dean Anderson's easy charisma made O'Neill the heart of the franchise, even as the actor stepped back to a recurring role.
